UNITED STATES noBER'r TLWRIGHn or INDEPENDENCE, KANSASt HAY PRESS.

Application led September 14, 1925. Serial No. 56,306.

Totali whom imag/concern.' r f Be it known that I, ROBERT T. VRiGH'r, a .citizen ofthe United States,fresiding at Independence, in the countyrof Montgomery and State of Kansas, have invented'certain new and useful improvements in a. Hay Press, of which the following is a specification. 'l p This invention relates to improvements: in hay presses, and particularly to the type of hay press wherein a reciprocating plunger mechanism operates two plungers within a pair of alined chambers for produc-ing a double output in a machine normally having only a single output in the application of the same amount of power.

An object of the invention resides in'proi viding a. frame work witlia pair of alined compression chambers in which operate a pair of spaced plungers for compressing material within the chambers and between which plungers isl positioned operating mechanism driving the plungers to compress material within the chambers which is of an adjustable character so that the timing of the stroke of operation can be variedV in its relation to the operation of the other mechanism of the machine. Y

Another object o f the invention lresides in i providing a press of the character above described, having rotary mechanism and adjustable connection between said rotary mechanism and a pair ofl spaced plungers at opposite sides lthereof' reciprocable in the compression chambers formed in the frame of the machine with which cooperate in timed relation, a mechanism on the top of the frame inthe feed hoppers forthe comp'ression chambers for forcingtlie material, said hoppers into thiscompression chamber in timed-relation with the operationof the plungers in order that the proper supply'of material will be made into the compression chambers between each compression stroke of the plunger. 1

The invention further comprehends iin- `arovements in the particular construction and operation of the means for forcing the material into the compression chambers, `together with the'operating means for the.

plungers and associated mechanism therewith and also tomechanism for maintaining the slotted separating member for the bales in compressed relation against 'said bales within the compression chamber until the vbaling wires have been applied.

The invention also comprehends improvements in the various details' of construction 1 and the arrangement ofthe arts 'shown andthe above and other ob]ects ofthe invention which are more particularly vpointed out inthe 'following detailed description and in the claims directed'to a preferred Y formof vthe invention, it being understood however, thatvarious changes inthe size, sliape 'and arrangement of the yparts 'may be made for producing the same result, which .constructions are clearly within the spirit f and scope of the invention as herein set forth..A Y Inthe drawings forming part of this application- ,l f

Y Fig. 3 is a plan view of the central portion of the machine.

Fig. t is a vertical sectionalviewtaken'on the line 4-4 of Fig. 3. I n I Fig. 5 is a detail perspective view of one of the plat'e'members of the feeding mechanism. v

Fig. 6 is a vertical longitudinal sectional view through 'the' portion 'centrali oft-he press, showingfparticularly the plunger operating mechanism.' v

Fig. 7 is a. horizontal-sectional view thru a 'portion ofone-of the compression chambers illustrating the manner in which the plunger voperates therein together withl the mechanism for holding the material and the separating plates for the bale'compr'es'sed in rel-ation. 'v fj The improved hay press comprises a main frame 1 which is composed of a plurality of longitudinally extending barr` members 2 mounted in spaced parallel relationand secured'together by a plurality of transversely Y' arranged frame members 3. v rlhis frame construction is supported upon trucks and 5 respectively, theV truclr5 being Yrelatively rotatable o n the frame for guiding lthe press when moved from place to place, whichA are provided with the wheels 6. Each of these trucks are provided with suitable bracing members 7 while the pivoted truck 5 has a tongue mechanism 8 for connection with a tractor or the like, when it is to be moved from place to place.

Bottom forming members or plates 9 are positioned between the bottom frame bars 2 to form the bottom of the compression chamber for receiving and conveying material under compression therein and at spaced intervals from the central portion of the frame are hopper members 10, while the remaining outer end portions of the upper frame bars 2 have top forming plates 11 mounted therein in spaced parallel relation above the bottom plates 9.

The compression chamber is formed immediately below the hoppers 10 and the sides of the frame are closed by side members 12 at this point in order that the reciprocation of the plungers 13 will compress hay or other material fed into the compression chambers Which are in spaced relation in the operation of the plungers in said chambers, so Athat bales of compressed materia-1 may be formed and forced outwardly` toward the end of the frame between the top and bottom plates in compressed relationin a manner which will presently appear.

Referring particularly to Fig. 6 which clearly illustrates the plunger mechanism, it will be seen that the plungers 13 are substantially large block members slidably mounted in axial relation in the compression chambers formed below the hoppers 10 and reciprocate in their movement throughout the extent of the compression chambers and slightly beyond the terminus of the hoppers as shown at right hand end of Fig. 6, compressing material in the chambers. The upper ends or top portion of the plungers 13 are recessed as at 14 slidably receiving the movable plate member 15 which is slotted as at 16 in the central portion and the end portions of which slidably l'it in said recesses 14. The central portion of this movable plate member 15 is provided with a pair of upwardly extending projections 17 at opposite sides thereof which carry rollers 18 adapted to ride on the upper surface of the frame bars 2 for supporting and guiding the movable plate mechanism in the operation of the plunger mechanism.

A suitable guard structure 19 is mounted above the frame bars 2 above the rollers 18 for preventing contact with the rollers in the operation of the plunger mechanism and also preventing loose material being compressed and from interfering with the operation of the movable plate members. Tongues 20 are mounted in recesses in the ends of the movable plate members 15 and project beyond the end portions thereof into slots 21 extending longitudinally in the upper face of the plunger 13, and which tongues are retained in said slots by the cross members 22, carried by the plungers.

U-shaped members 23 are mounted on the adjacent ends of the plungers 13 as illustrated in Fig. 6, and have the leg portions thereof pro-vided with a plurality of openings 24 for receiving the hinged ends 25 for the adjustable connecting rod mechanism 26. This connecting rod mechanism comprises a pair of sections 27 and 28, the section 27 being provided with a looped central portion mounted on the hinged end 25, while the section 28 comprises a substantially large looped portion V29 mounted in the annular recess of the cam 30. This cam 30 is provided with a pair of adjacent annular recesses for the member 28 of each connecting rod mechanism, while a suitable securing mechanism 31 serves to secure the end portions of the members 27 and 28 in assembled relation. This cam member 30 is eccentrically mounted on the shaft 32 which is rotatably mounted in the bearing bars 33 carried by the frame of the press.

On one end of the shaft 32 there is mounted the spur gear 34 with which meshes the reducing gearing 35 rotatably mounted on the stub shaft 36 carried by one of the bearing bars 33 while the shaft 37 mounts the drive pulley 38 provided with a spur gear for driving the reducing gearing 35, and in turn driving shaft 32 for operating the plunger mechanism.

The position of the hinge pins in the U- shaped bracket 23 adjusts the length of the stroke of the plunger 13 according to the position of said hinge pins in the openings 24 of said bracket, so that the operation of the machine may be varied within the desired limits.

Pairs of hook members are pivotally mounted at opposite sides of each lcompression chamber in the framemember, and have the hooked ends 40 extending thru openings 41 in the side plates 12 carried by the frame. The end portions of these hooks project into the compression chamber as shown in Figs. 6 and 7, and serve to engage the material compressed in said chamber to retain the same in compressed relation outwardly 0f the hook and within the frame and also to retain the separating plates 42 at the outer end of the compression stroke so that the material will be retained in cornpression until baling wires can be inserted around the bales thru the slots 43 formed in the separating plates.

Bracket members 44 are-mounted on the transverse frame forming bars 3 over the hooks 39 and form an abutment for coiled springs 45 encircling the guide pins 46 thereof which are adapted to normally retain the hooks 39 in the posit-ion shown in 'use Fig.V i. bar 47 vextending between the hooks 39 and connected therebyfby locking members 48 at the endsof the cross bar 47. It-will be thus seen `that the coiled springs 45 normally retain the pairs .of hook members in `operative position kto retain material pressed by the plungers in compressed relation so as to hold lthe separating plates while at the time being yieldable to permit the passage of. the material being compressed as well as the operation of the plunger in moving the material beyond said hook. y 1

l, The press is provided' with a feeding mechanism, more particularly illustrated in Figs. 1 and 2 which includes a pair of uprights 50 mounted in spaced parallel relation on opposite'sides ofthe frame and secured to the frame bars 2, the end portions of which extend upwardly above the frame bars for rockably mounting the rock shaft 51 in theI upper ends thereof which mounts an operating arm 52 on one end connected by the pitman 53 with the `crank pins 54 on the disks 55 mounted on the shaft 2, so that the rotation of said shaft, the rockingmovement will Vbe. imparted to the rock shaft 51 for operating the. feeding mechanism for the press. v 1

This feeding mechanism comprises a pair of spaced'bar members 56 forming a rocking memberand which bars are mounted in their y central portions on the rookshaft 51 for movement therewith. The end `portions of the shaft are bent irl-'angular relation and extend downwardly and between the free ends, pivotally mount the plate members 57 The head 58 forming part of the plate members or the portions pivotally mounted in the bar 56, are mounted so that the plate portions may be renewed when they become worn or broken without dis-assembling the rocking member.

Levers 59 are pivotally mounted in their central portionswith between.r the bars 56 intermediate the central portionin the op-Y posite end as clearly illustrated in Fig. 2, and have Vthe lower ends connected by the links 60 withthe blade members 57 below'V the pivotal mounting in the bars 56. The upper ends of these levers 59V are connected by the coiled springs 61 which are constantly undertension. Ring members 62 forming operating links are pivotally mountedon 'a cross bar pivotallyconnected to the levers 59 below the pivotal mounting thereof between the bars 56, so that in the rocking of the rocking member 56, the blade 57 will be caused to have a pivotal mounting in the rocking member so as to maintain the blades ina Vsubstantially upright position and produce a slight movement thereof toward the outer end of the frame so that the blade mem- Thcse spring'sbear upon the crossV 63 mounted in the upri'ghts 50 and bers willy rforce the material within the hoppers as they move downwardly there? in into the compression chambers in front of the plungers and slightlyl forward or out# wardk toward the ends kof the frame so lthat the chambers will be completely filled with material and placed under slight compression. Suitable sleeves 64 maybe mounted on the rock shaft 51 and also the rock shaft 63 as illustrated in Fig.,4, for maintaining the rock member and the operating link 62 in proper operative position. U-shaped bracing members' 65 have their free ends conf soY in the hoppers from fouling theV mechanism thereunder.

In operation, the pulley 38 is rotated from a suitable motor, either .mounted on the frame bars 2 or from a separate power unit by a belt connection whichrotates the shaft 52 and operates the cam 30 which in turn vproduces a reciprocating movement of the plungers 13 in the frame and in the compression chambers which are supplied with v material throughv the rocking voperation of the rock member and the operation of the blades 57 for forcing materials into the hoppers k10 into the compression chambers in timed relation so that the. blades operate to forcel material into the compression chambers when the plunger of the particular chamber is in retracted position. v

The plungers 13 throughthe operation of the cam will beldrawn during one stroke of movement toward each other when the center of the cam lis at right angles tothe axis of the shaft 32 as compared with the longitudinal axis of the machine and will be sepa'- rated or moved to a greater distance apart in the position shown in Fig. 6 which is compensated for by theshortness of the plate 15 which forms a means of preventing the materialto be compressed from falling from the hopper into the operating mechanism and'thereby interfering with the efficient op-` eration. AThis plate mechanism which is rsupported on the rollers '18 reciprocate through'y the operation of the plunger.

Atthe outer limit of movement vof each plunger 13, vthe Aend portion of the same engagesthe ends 40 of the hook members 39 and forces thev same outwardly against the tension of the springs- 45 so as to force terial being compressed in the ends of the hook or to move one of the separating plates 42 beyondfthe hooks so that the material is retained in compressed relation while the plunger is withdrawn forl receiving anew charge of material in the compression chamber.

The plungers 13 are alternately moved thru their compression stroke as will be clear from Fig. 6, it will be seen that only sufficient power is necessary for operating one of the plungers which is taken advantage of for operating a double compressing mechanism mounted in axial alinement and operating in opposite directions for increasing the production of one machine.

The position of the disk member 55 on the shaft 32 is such that the rock member formed by the bars 56 will be operated in such timed relation with the plunger 13 that the blades will be moved downwardly and outwardly toward the end portions through the operation of the link 62 for supplying material within the hoppers to the compression chambers when the plungers are in their retracted positions.

It should thus be appreciated that substantially etlicient yet simpe machine construction has been provided for producing a hay press in which substantially novel structures exist in the operation of the plunger mechanism and the construction and operation of the machine feeding' mechanism together with the hook members for holding the material in compressed relation.

t is to be understood that the brace members 7 are preferably removable in order that they may be removed at one end when it is desired to move the machine from place to place to permit steering. In view of the braces at both ends being removable, the machine may be moved in either direction without turning it around fortthe purpose.

Having thus described my invention, what l caim as new is l. A hay press comprising a frame structure provided with a pair of baling chambers, a pair of plunger-s operating in axial alinement in said baling chambers, and operating mechanism between said plungers including bracket members mounted on said plungers, a shaft rotatable in said frame work between said plungers, an eccentric mounted on said shaft and connecting rod mechanisms mounted on and operable by said eccentric having adjust-able connection with the bracket members on said plungers, and operating means for rotating said shaft.
